Oil flows through your automatic transmission and power steering systems to transmit power, lubricate parts and provide cooling. Contaminants (like dirt, metal fragments and fibers) result in the oil working like sandpaper. Instead reducing friction the oil gradually wears out the parts it's supposed to protect. Under normal driving conditions, the oil can be contaminated in just 25 hours of driving.
These filters stop ferrous metal below the sub-micron level! The remaining metal and dirt is stopped by the paper element. Installing a Magnafine in-line filter will remove 99.997% of damaging contamination, making the oil cleaner than when your vehicle first left the factory. Best yet, it will keep it that way.
